Perhaps this is why Peter Brant couldn’t divorce Stephanie Seymour a few years ago.

Former Sports Illustrated Swimsuit model Seymour, 44, showed off a figure that’s still camera ready in a one-piece bathing suit while on vacation in St. Barth’s during the holidays. She was also spotted wearing a two-piece red bikini right before Christmas, which showed off her toned tummy and perky bosom.

The fit mother of four was on vacation with her ever entertaining Brant brood, Peter Brant, Jr., Harry Brant and Lily. Seymour also has a son, Dylan with former husband Tommy Andrews.

Seymour and Brant were headed for divorce in 2009 after 14 years of marriage. But after a bitter court battle that went on for a year, the two had a change of heart and reconciled.

Seymour in September appeared on a controversial cover of Vogue Hommes International. Critics panned the cover — which showed a male model grabbing Seymour by the neck while groping her chest — for promoting domestic violence.
